For this AnimationNode experiment I made growing vines out of vertices using random 2d noise patterns.
I used a grid mesh to generate the inital vertices and iterate over the list of vertices in the mesh using a loop.
Then I used a second loop to generate the spline for each vertex.

The number of vertices in each spline is controlled by the framerate and each vertex is moved by a random amount along the x- and y-axis.

For this animation nodes experiment I created a group of spheres and calculated their sizes so that they touch but never overlap. I iterated over the list of positions and calculated the distances to all other spheres using a Vector Distance Node. Then I sorted the list of distances and took the second entry to get the minimal distance to a different node (the first entry is always zero - its the distance of the current sphere to it self). The sphere is then scaled to half of the minimum distance to make sure no spheres overlap

For this animation node experiment I used the Vector Noise node to create displacements of the mesh vertices of a icosphere along their normal vector. This creates a similar effect to using the displacement modifier with a noise texture, but you could use any node setup instead of the simple noise I used to create crazy complex animated displacements.

I printed a 2,4,6-Trinitrotoluol molecule - better known by its abbrevation TNT - on my 3D printer this weekend. I constructed a tetraedic and a hexagonal basic shape using openscad and printed the atoms in different colors. I originally intended to connect the atoms using double sided tape but the molecule got pretty unstable and fell apart spontaneously. So I used some hotglue to glue the atoms together.

I finally managed to fix all my python and cython version missmatch errors and started experimenting with a animation nodes 2.1 development branch - this is my first experiment using the vector noise node and the curly noise setup described in the brilliant blender.stackexchange.com answer by omar Ahmad

you can download the blend file here but be aware that the 2.1 branch of the Animation Node Addon is currently under heavy development so maybe the examples here won't work out of the box with a final version.
